Power output device, ice crusher and refrigerator

Abstract

The invention provides a power output device, an ice crusher and a refrigerator. According to the power output device, except for the motor and the mounting screws, all the power output device is formed by engineering plastics, the brushless motor is selected as a power source, and the brushless motor drives the gear train to achieve integrated output shaft output. The internal structure is more compact, the thickness of the gearbox shell of the power output device can be effectively compressed to be within 30 mm, the requirements of customers for light and thin products are met, and the space utilization rate of a refrigerator is increased. The brushless motor is high in safety and can meet the IEC explosion-proof test standard, the rotating speed and the rotating direction can be flexibly adjusted through a driving algorithm, the phenomena of ice clamping and rotation blocking are effectively reduced, and the ice crushing effect is optimized. According to the ice crusher, the output shaft integrally formed by engineering plastics is adopted, and the structure of the output shaft can realize power output without assembly and matching, so that faults caused by unreliable assembly among mechanical parts can be effectively avoided, and the use feeling of the ice crusher is improved.

Description

technical field [0001] The present application relates to the field of refrigerator parts, in particular to a power output device, an ice crusher and a refrigerator. Background technique [0002] The existing ice crushers on the market are relatively large in size. The thickness of the shell of the power output device is usually more than 42mm, which will directly affect the utilization rate of the interior space of the refrigerator. Therefore, considering the integrated space arrangement inside the refrigerator, a new type of flat ice crusher power output device needs to be designed. [0003] In addition, ice crushers are sold on the market, and their internal power source usually uses a brushed DC motor. There are carbon brushes inside the brushed motor, and sparks are generated when the carbon brushes switch the connection electrodes. The internal structure of this motor cannot meet the IEC explosion-proof test standards [0004] Moreover, since the brushed motor has ...
